The 205 type dual beam ultraviolet ozone analyzer from 2B Company in the United States adopts the latest 254nm ultraviolet dual beam light source technology and design, which can simultaneously measure the ozone value of the tested sample and the purified air value after ozone removal. Combined with other patented technologies, the 205 dual beam ultraviolet ozone analyzer has a measurement response time of only 2 seconds, making it the fastest response time ozone analyzer on the market. The instrument range ranges from 1ppbv to 100ppmv. This instrument has high precision (1 ppb), small size, light weight (5 pounds, 2.3 kg), and low power consumption. Especially suitable for atmospheric ozone measurement in aerospace and balloons.

Application of Model 205 Dual Beam UV Ozone Analyzer:

• Atmospheric measurement of balloons and aviation
• Establish a remote monitoring network
• Establish a city monitoring network
• Personal and work environment monitoring
• Monitoring in industrial production

Model 205 Dual Beam UV Ozone Analyzer Product Features:

• Using dual beam 254nm ultraviolet absorption method
• High precision and resolution, with a range from 1ppbv to 100ppmv
• 2-second response time, superior to similar products
• Low battery consumption, capable of operating with an external power supply of 12V DC (5.0W)
• DewLineTM technology reduces the interference of water vapor on instruments
• Built in data recording function and real-time clock display. And there are 3 sets of simulated signal outputs
• Output time, date, ozone concentration, instrument temperature, air pressure, and three additional sets of supplementary input signals via RS-232, such as external temperature, humidity, and air pressure
• Analog output 0-2.5V
• Optional GPS function and CF memory card

The 205 dual beam ozone analyzer simultaneously measures the current values of Io (air with purified ozone) and I (air without purified ozone). Making the time interval for ozone measurement reach 2 seconds, it has become the fastest ozone analyzer based on ultraviolet method on the market, measuring the concentration of ozone in the environment up to 100ppm, while retaining the characteristics of small size, light weight, and low power consumption. Rapid measurement is particularly desirable for aircraft and balloon measurements of ozone, where high-altitude solutions are crucial. As a choice, users can choose the average of multiple internal points to achieve better accuracy.

Options:

1: Hard protective carrying case;
2: Long life battery, suitable for long-term power supply in the field or when there is no mains power
